Abstract

Ba4Ir3O10 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.74–3.08 Å. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.60–3.00 Å. There are two inequivalent Ir4+ sites. In the first Ir4+ site, Ir4+ is bonded to six O2- atoms to form face-sharing IrO6 octahedra. There are two shorter (2.06 Å) and four longer (2.07 Å) Ir–O bond lengths. In the second Ir4+ site, Ir4+ is bonded to six O2- atoms to form a mixture of corner and face-sharing IrO6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Ir–O bond distances ranging from 2.00–2.15 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to four Ba2+ and one Ir4+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two Ir4+ atoms.
